Interface ServicesManager

All Known Implementing Classes:
SimpleServicesManager
public interface ServicesManager
Manages services and service providers. Services are an interface specifying a list of methods that a provider must implement. Providers are implementations of these services. A provider can be queried from the services manager in order to use a service (if one is available). If multiple plugins register a service, then the service with the highest priority takes precedence.
